Description

クラッチ装置Clutch device
 本発明は、エンジンからトランスミッションへ動力を伝達するためのクラッチ装置に関する。 The present invention relates to a clutch device for transmitting power from an engine to a transmission.
 車両の変速を自動的に行う手段として自動変速機(AT)が知られている。近年のATは、例えばトルクコンバータ、複数の遊星ギヤおよびクラッチを組み合わせたものが主流となっている。トルクコンバータの無段変速作用および複数のクラッチの自動切換により、ATは手動変速機(MT)で必要とされている発進時、停止時および変速時のドライバーによるクラッチ操作が不要になる。 An automatic transmission (AT) is known as a means for automatically shifting a vehicle. In recent years, for example, a combination of a torque converter, a plurality of planetary gears, and a clutch has become mainstream. Due to the stepless speed change operation of the torque converter and the automatic switching of the plurality of clutches, the AT does not require clutch operation by the driver at the time of starting, stopping and shifting required for the manual transmission (MT).
 しかし、トルクコンバータは流体を介して動力を伝達するので、入力側と出力側とを機械的に直接連結しトルクを伝達するMTに比べて、ATは動力伝達効率が低下する。したがって、ATは、ドライバーの労力が軽減されるという利点を有している反面、車両の燃費が低下するという欠点を有している。
 そこで、MTの伝達効率を確保しつつクラッチ操作を不要とすることを目的として、MTの構造をベースとした自動変速機(AMT)が提案されている。この自動変速機では、MTのクラッチ操作およびトランスミッションの変速操作が自動化されている。この自動変速機により、従来のMTと同様の伝達効率を確保しつつ、クラッチ操作を不要とすることができる。
However, since the torque converter transmits power via a fluid, AT has lower power transmission efficiency than MT that mechanically directly connects the input side and output side to transmit torque. Therefore, the AT has an advantage that the labor of the driver is reduced, but has a disadvantage that the fuel consumption of the vehicle is reduced.
Therefore, an automatic transmission (AMT) based on the structure of MT has been proposed for the purpose of eliminating the need for clutch operation while ensuring MT transmission efficiency. In this automatic transmission, MT clutch operation and transmission shift operation are automated. This automatic transmission can eliminate the need for clutch operation while ensuring the same transmission efficiency as that of the conventional MT.
 しかし、変速操作をする間はMTと同様にクラッチの連結を解除するので、トルク伝達が一時的に遮断される。トルク伝達が遮断される間は、車両が加速することなく慣性のみで走行する。このようなトルク切れは、車両の加速性能に大きく影響するとともに、ドライバーに不快感を与えやすい。
 そこで、このトルク切れの問題を解決するため、ツインクラッチ装置を採用した自動変速機が提案されている(例えば、特許文献1を参照)。
However, during the shifting operation, the clutch is disengaged in the same manner as MT, so torque transmission is temporarily interrupted. While the torque transmission is interrupted, the vehicle travels only with inertia without acceleration. Such torque loss greatly affects the acceleration performance of the vehicle and tends to make the driver uncomfortable.
In order to solve this problem of torque interruption, an automatic transmission employing a twin clutch device has been proposed (see, for example, Patent Document 1).

However, in the case of a wet type, it is necessary to realize a seal structure, so that the structure becomes complicated.
Therefore, a dry clutch device has been proposed.
However, in the dry type, the structure can be simplified as compared with the wet type, but the performance of the clutch device may vary due to wear of the clutch disk.

 第1アジャストボルト153は、第1ダイヤフラムスプリング71の押圧力を第1プレッシャプレート39に伝達するように配置されており、第1プレッシャプレート39に装着されている。具体的には、第1アジャストボルト153は、第1ネジ部153cを有する概ね筒状の第1ボルト本体153aと、第1ボルト本体153aから半径方向内側に突出した環状の第1当接部153bと、を有している。 The first adjustment bolt 153 is disposed so as to transmit the pressing force of the first diaphragm spring 71 to the first pressure plate 39, and is attached to the first pressure plate 39. Specifically, the first adjustment bolt 153 includes a generally cylindrical first bolt main body 153a having a first screw portion 153c, and an annular first contact portion 153b protruding radially inward from the first bolt main body 153a. And have.
 第1ボルト本体153aが第1ネジ孔163aにねじ込まれているので、第1ボルト本体153aは第1プレッシャプレート39に対して回転すると第1プレッシャプレート39に対して軸方向に移動する。第1ボルト本体153aには第1アジャストスプリング154により回転力が常に付与されている。より詳細には、第1アジャストボルト153が第1プレッシャプレート39に対してトランスミッション側に移動するように、第1アジャストボルト153には第1アジャストスプリング154により回転力が付与されている。 Since the first bolt body 153a is screwed into the first screw hole 163a, the first bolt body 153a moves in the axial direction with respect to the first pressure plate 39 when rotated with respect to the first pressure plate 39. A rotational force is always applied to the first bolt body 153 a by the first adjustment spring 154. More specifically, a rotational force is applied to the first adjustment bolt 153 by the first adjustment spring 154 so that the first adjustment bolt 153 moves toward the transmission side with respect to the first pressure plate 39.
 また、第1ボルト本体153aには、中間部材78の端部が挿入されている。第1ボルト本体153aは第1テーパ面153fを有しており、第1テーパ面153fは中間部材78の端部と当接している。
 第1当接部153bは、環状の部分であり、第1スライドブッシュ152の第1規制部152b(後述)と軸方向に当接している。第1当接部153bには第1スライドブッシュ152が挿入されている。
Further, the end of the intermediate member 78 is inserted into the first bolt main body 153a. The first bolt main body 153 a has a first tapered surface 153 f, and the first tapered surface 153 f is in contact with the end portion of the intermediate member 78.
The first contact portion 153b is an annular portion, and is in contact with a first restriction portion 152b (described later) of the first slide bush 152 in the axial direction. A first slide bush 152 is inserted into the first contact portion 153b.
 第1スライドブッシュ152は、第1アジャストボルト153のエンジン側への移動を規制するための部材であり、第1プレッシャプレート39に対して軸方向に移動可能に第1プレッシャプレート39により支持されている。第1スライドブッシュ152は第1プレッシャプレート39からエンジン側に突出している。第1スライドブッシュ152のトランスミッション側の端部は第1アジャストボルト153の第1ボルト本体153aに挿入されている。第1スライドブッシュ152は第1アジャストボルト153と同心円状に配置されている。 The first slide bush 152 is a member for restricting the movement of the first adjustment bolt 153 to the engine side, and is supported by the first pressure plate 39 so as to be movable in the axial direction with respect to the first pressure plate 39. Yes. The first slide bush 152 protrudes from the first pressure plate 39 to the engine side. The end of the first slide bush 152 on the transmission side is inserted into the first bolt body 153a of the first adjustment bolt 153. The first slide bush 152 is disposed concentrically with the first adjustment bolt 153.
 第1スライドブッシュ152は、概ね筒状の第1スライドブッシュ本体152aと、第1スライドブッシュ本体152aから半径方向外側に突出した概ね環状の第1規制部152bと、第1引っ掛け部152dと、を有している。第1スライドブッシュ本体152aは外径が小さくなった状態で第1支持孔163bに挿入されている。具体的には、第1スライドブッシュ本体152aには軸方向に細長く延びる第1スリット152cが形成されている。第1スリット152cが形成されているので、第1スライドブッシュ本体152aは径方向に弾性変形可能となっている。第1スライドブッシュ本体152aは第1プレッシャプレート39の第1支持孔163bに締まり嵌めされているので、第1スライドブッシュ152が第1プレッシャプレート39に対して軸方向に移動したり、あるいは回転したりすると、第1スライドブッシュ152と第1プレッシャプレート39との間には比較的大きな摺動抵抗が発生する。したがって、基本的には、第1スライドブッシュ152は第1プレッシャプレート39と一体となって軸方向に移動するが、第1スライドブッシュ152に比較的大きな軸方向の力が作用すると、第1プレッシャプレート39に対して第1スライドブッシュ152が軸方向に移動する。 The first slide bush 152 includes a generally cylindrical first slide bush main body 152a, a generally annular first restricting portion 152b projecting radially outward from the first slide bush main body 152a, and a first hooking portion 152d. Have. The first slide bush main body 152a is inserted into the first support hole 163b with the outer diameter reduced. Specifically, a first slit 152c extending in the axial direction is formed in the first slide bush main body 152a. Since the first slit 152c is formed, the first slide bush main body 152a can be elastically deformed in the radial direction. Since the first slide bush body 152a is tightly fitted in the first support hole 163b of the first pressure plate 39, the first slide bush 152 moves in the axial direction with respect to the first pressure plate 39 or rotates. In this case, a relatively large sliding resistance is generated between the first slide bush 152 and the first pressure plate 39. Therefore, basically, the first slide bush 152 moves integrally with the first pressure plate 39 in the axial direction. However, when a relatively large axial force acts on the first slide bush 152, the first pressure is applied. The first slide bush 152 moves in the axial direction with respect to the plate 39.
 第1規制部152bは、第1ボルト本体153aの内側に配置されており、第1当接部153bのトランスミッション側に配置されている。第1規制部152bは第1当接部153bと軸方向に当接している。第1スリット152cは第1規制部152bまで延びているので、第1規制部152bはC字状となっている。第1スリット152cには第1アジャストスプリング154の第2端154c(後述)が挿入されている。 The first restricting portion 152b is disposed inside the first bolt main body 153a, and is disposed on the transmission side of the first contact portion 153b. The first restricting portion 152b is in contact with the first contact portion 153b in the axial direction. Since the first slit 152c extends to the first restricting portion 152b, the first restricting portion 152b has a C shape. A second end 154c (described later) of the first adjustment spring 154 is inserted into the first slit 152c.
 第1引っ掛け部152dは、第1スライドブッシュ152の第1円板部33側の端部に形成されており、第1スライドブッシュ本体152aから半径方向内側に突出する概ね環状の部分である。第1引っ掛け部152dは第1ストッパ151のストッパ部151bと当接可能に設けられている。第1ストッパ151は第1引っ掛け部152d内に挿入されている。 The first hook portion 152d is formed at the end of the first slide bush 152 on the first disc portion 33 side, and is a substantially annular portion that protrudes radially inward from the first slide bush body 152a. The first hooking portion 152d is provided so as to be in contact with the stopper portion 151b of the first stopper 151. The first stopper 151 is inserted into the first hook portion 152d.
 第1アジャストスプリング154は、捩じりコイルバネであり、第1アジャストボルト153に回転力を付与している。第1アジャストスプリング154は、第1アジャストボルト153が第1プレッシャプレート39に対してトランスミッション側に移動するように、第1アジャストボルト153に回転力を付与している。
 具体的には、第1アジャストスプリング154は、第1スプリング本体154aと、第1端154bと、第2端154cと、を有している。第1スプリング本体154aは、回転力を発生する部分であり、第1アジャストボルト153の内周側に配置されている。第1端154bは、第1スプリング本体154aのエンジン側の端部から突出しており、第1アジャストボルト153に引っ掛けられている。
The first adjustment spring 154 is a torsion coil spring and applies a rotational force to the first adjustment bolt 153. The first adjustment spring 154 applies a rotational force to the first adjustment bolt 153 so that the first adjustment bolt 153 moves toward the transmission side with respect to the first pressure plate 39.
Specifically, the first adjustment spring 154 has a first spring body 154a, a first end 154b, and a second end 154c. The first spring body 154 a is a part that generates a rotational force, and is disposed on the inner peripheral side of the first adjustment bolt 153. The first end 154 b protrudes from the end of the first spring body 154 a on the engine side and is hooked on the first adjustment bolt 153.
 例えば、第1端154bは第1アジャストボルト153の第1引っ掛け孔153dに挿入されている。第2端154cは、第1スプリング本体154aの第1スライドブッシュ152側の端部から突出しており、第1スライドブッシュ152に引っ掛けられている。例えば、第2端154cは第1スライドブッシュ152の第1スリット152cに挿入されている。第1スライドブッシュ152は第1支持孔163bに締まり嵌めされているので、第1スライドブッシュ152が第1プレッシャプレート39に対して軸方向に移動したり、あるいは回転したりすると、第1スライドブッシュ152と第1プレッシャプレート39との間には比較的大きな摺動抵抗が発生する。第1アジャストスプリング154が第1アジャストボルト153に付与する回転力は第1スライドブッシュ152を回転させるほど大きくはないので、第1スライドブッシュ152は第1プレッシャプレート39に対する第1アジャストスプリング154の回転を規制することができる。 For example, the first end 154b is inserted into the first hooking hole 153d of the first adjusting bolt 153. The second end 154 c protrudes from the end of the first spring body 154 a on the first slide bush 152 side and is hooked on the first slide bush 152. For example, the second end 154 c is inserted into the first slit 152 c of the first slide bush 152. Since the first slide bush 152 is tightly fitted in the first support hole 163b, when the first slide bush 152 moves in the axial direction with respect to the first pressure plate 39 or rotates, the first slide bush 152 A relatively large sliding resistance is generated between 152 and the first pressure plate 39. Since the rotational force that the first adjustment spring 154 applies to the first adjustment bolt 153 is not so great as to rotate the first slide bush 152, the first slide bush 152 rotates the first adjustment spring 154 relative to the first pressure plate 39. Can be regulated.
 第1ストッパ151は、第1フライホイール3の第1円板部33に固定されており、第1フライホイール3に対する第1プレッシャプレート39の軸方向の移動を規制する。具体的には、第1ストッパ151は、第1スライドブッシュ152に挿入されており、第1スライドブッシュ152と軸方向に当接可能に配置されている。動力伝達時において、第1ストッパ151と第1スライドブッシュ152との間には隙間G1が形成されている。この隙間G1はレリーズ時の第1プレッシャプレート39のリフト量に相当している。したがって、第1摩擦部57が摩耗しても、第1スライドブッシュ152および第1ストッパ151により第1プレッシャプレート39のリフト量が一定に保たれる。 The first stopper 151 is fixed to the first disc portion 33 of the first flywheel 3 and restricts the axial movement of the first pressure plate 39 relative to the first flywheel 3. Specifically, the first stopper 151 is inserted into the first slide bush 152 and is disposed so as to be able to contact the first slide bush 152 in the axial direction. During power transmission, a gap G1 is formed between the first stopper 151 and the first slide bush 152. This gap G1 corresponds to the lift amount of the first pressure plate 39 at the time of release. Therefore, even if the first friction portion 57 is worn, the lift amount of the first pressure plate 39 is kept constant by the first slide bush 152 and the first stopper 151.
 第1ストッパ151は、第1スライドブッシュ152および第1プレッシャプレート39のトランスミッション側への移動を規制するために設けられており、第1円板部33にねじ込まれたストッパ本体151aと、ストッパ本体151aの端部に形成されたストッパ部151bと、を有している。ストッパ部151bはストッパ本体151aから半径方向外側に突出した環状の部分である。ストッパ部151bは前述の第1スライドブッシュ152の第1引っ掛け部152dと当接可能となっている。第1ストッパ151は第1アジャストボルト153および第1スライドブッシュ152と同心円状に配置されている。具体的には図3に示すように、第1ストッパ151、第1アジャストボルト153および第1スライドブッシュ152の中心軸はラインB1となっている。 The first stopper 151 is provided to restrict the movement of the first slide bush 152 and the first pressure plate 39 to the transmission side, and includes a stopper main body 151a screwed into the first disc portion 33, and a stopper main body. And a stopper portion 151b formed at the end portion of 151a. The stopper portion 151b is an annular portion that protrudes radially outward from the stopper body 151a. The stopper portion 151b can come into contact with the first hook portion 152d of the first slide bush 152 described above. The first stopper 151 is disposed concentrically with the first adjustment bolt 153 and the first slide bush 152. Specifically, as shown in FIG. 3, the central axes of the first stopper 151, the first adjustment bolt 153, and the first slide bush 152 are a line B1.
 <第2摩耗追従機構200>
 複数の第2摩耗追従機構200は、第2クラッチC2の第2摩擦部67の摩耗によるクラッチ装置1の性能の低下を抑制するための機構であり、円周方向に等間隔に配置されている。第2摩耗追従機構200は第1摩耗追従機構100同士の間に配置されている。具体的には図6および図7に示すように、各第2摩耗追従機構200は、第2アジャストボルト253(第1調整部材または第2調整部材の一例)と、第2アジャストスプリング254(第1弾性部材または第2弾性部材の一例)と、第2スライドブッシュ252(第1検出部材または第2検出部材の一例)と、第2ストッパ251(第1ストッパ部または第2ストッパ部の一例)と、を有している。

And have.
 第2ボルト本体253aが第2ネジ孔263aにねじ込まれているので、第2ボルト本体253aは第2プレッシャプレート49に対して回転すると第2プレッシャプレート49に対して軸方向に移動する。第2ボルト本体253aには第2アジャストスプリング254により回転力が常に付与されている。より詳細には、第2アジャストスプリング254が第2プレッシャプレート49に対して第1円板部33側に移動するように、第2ボルト本体253aには第2アジャストスプリング254により回転力が常に付与されている。さらに、第2ボルト本体253aは第2テーパ面253fを有しており、第2テーパ面253fは連結ロッド79のキャップ部79bと当接している。 Since the second bolt body 253a is screwed into the second screw hole 263a, the second bolt body 253a moves in the axial direction with respect to the second pressure plate 49 when rotated with respect to the second pressure plate 49. A rotational force is always applied to the second bolt main body 253a by the second adjustment spring 254. More specifically, a rotational force is always applied to the second bolt body 253a by the second adjustment spring 254 so that the second adjustment spring 254 moves toward the first disc portion 33 with respect to the second pressure plate 49. Has been. Further, the second bolt main body 253 a has a second tapered surface 253 f, and the second tapered surface 253 f is in contact with the cap portion 79 b of the connecting rod 79.
 第2当接部253bは、環状の部分であり、第2スライドブッシュ252の第2規制部252b(後述)と軸方向に当接している。第2当接部253bには第2スライドブッシュ252が挿入されている。
 第2スライドブッシュ252は、第2アジャストボルト253のエンジン側への移動を規制するための部材であり、第2プレッシャプレート49に対して軸方向に移動可能に第2プレッシャプレート49により支持されている。第2スライドブッシュ252は第2プレッシャプレート49からエンジン側に突出している。第2スライドブッシュ252のトランスミッション側の端部は第2アジャストボルト253の第2ボルト本体253aに挿入されている。第2スライドブッシュ252は第2アジャストボルト253と同心円状に配置されている。
The second contact portion 253b is an annular portion, and is in contact with a second restriction portion 252b (described later) of the second slide bush 252 in the axial direction. A second slide bush 252 is inserted into the second contact portion 253b.
The second slide bush 252 is a member for restricting the movement of the second adjustment bolt 253 to the engine side, and is supported by the second pressure plate 49 so as to be movable in the axial direction with respect to the second pressure plate 49. Yes. The second slide bush 252 protrudes from the second pressure plate 49 to the engine side. An end of the second slide bush 252 on the transmission side is inserted into the second bolt body 253a of the second adjustment bolt 253. The second slide bush 252 is disposed concentrically with the second adjustment bolt 253.
 第2スライドブッシュ252は、概ね筒状の第2スライドブッシュ本体252aと、第2スライドブッシュ本体252aから半径方向外側に突出した概ね環状の第2規制部252bと、を有している。第2スライドブッシュ本体252aは外径が小さくなった状態で第2支持孔263bに挿入されている。具体的には、第2スライドブッシュ本体252aには軸方向に細長く延びる第2スリット252cが形成されている。第2スリット252cが形成されているので、第2スライドブッシュ本体252aは径方向に弾性変形可能となっている。第2スライドブッシュ本体252aは第2プレッシャプレート49の第2支持孔263bに締まり嵌めされているので、第2スライドブッシュ252が第2プレッシャプレート49に対して軸方向に移動したり、あるいは回転したりすると、第2スライドブッシュ252と第2プレッシャプレート49との間には比較的大きな摺動抵抗が発生する。したがって、基本的には、第2スライドブッシュ252は第2プレッシャプレート49と一体となって軸方向に移動するが、第2スライドブッシュ252に比較的大きな軸方向の力が作用すると、第2プレッシャプレート49に対して第2スライドブッシュ252が軸方向に移動する。 The second slide bush 252 has a generally cylindrical second slide bush main body 252a and a generally annular second restricting portion 252b protruding radially outward from the second slide bush main body 252a. The second slide bush main body 252a is inserted into the second support hole 263b with the outer diameter being reduced. Specifically, a second slit 252c extending in the axial direction is formed in the second slide bush main body 252a. Since the second slit 252c is formed, the second slide bush main body 252a can be elastically deformed in the radial direction. Since the second slide bush body 252a is tightly fitted in the second support hole 263b of the second pressure plate 49, the second slide bush 252 moves or rotates in the axial direction with respect to the second pressure plate 49. As a result, a relatively large sliding resistance is generated between the second slide bush 252 and the second pressure plate 49. Therefore, basically, the second slide bush 252 moves in the axial direction integrally with the second pressure plate 49, but when a relatively large axial force acts on the second slide bush 252, the second pressure is applied. The second slide bush 252 moves in the axial direction with respect to the plate 49.
 第2規制部252bは、第2ボルト本体253aの内側に配置されており、第2当接部253bの第1円板部33側に配置されている。第2規制部252bは第2当接部253bと軸方向に当接している。第2スリット252cは第2規制部252bまで延びているので、第2規制部252bはC字状となっている。第2スリット252cには第2アジャストスプリング254の第2端254c(後述)が挿入されている。 The second restricting portion 252b is disposed inside the second bolt main body 253a, and is disposed on the first disc portion 33 side of the second contact portion 253b. The second restricting portion 252b is in contact with the second contact portion 253b in the axial direction. Since the second slit 252c extends to the second restricting portion 252b, the second restricting portion 252b is C-shaped. A second end 254c (described later) of the second adjustment spring 254 is inserted into the second slit 252c.
 第2アジャストスプリング254は、捩じりコイルバネであり、第2アジャストボルト253に回転力を付与している。第2アジャストスプリング254は、第2アジャストボルト253が第2プレッシャプレート49に対してトランスミッション側(第2円板部43側)に移動するように、第2アジャストボルト253に回転力を付与している。
 具体的には、第2アジャストスプリング254は、第2スプリング本体254aと、第1端254bと、第2端254cと、を有している。第2スプリング本体254aは、回転力を発生する部分であり、第2アジャストボルト253の内周側に配置されている。第2端254bは、第2スプリング本体254aのエンジン側の端部から突出しており、第2アジャストボルト253に引っ掛けられている。
The second adjustment spring 254 is a torsion coil spring and applies a rotational force to the second adjustment bolt 253. The second adjustment spring 254 applies a rotational force to the second adjustment bolt 253 so that the second adjustment bolt 253 moves toward the transmission side (second disc portion 43 side) with respect to the second pressure plate 49. Yes.
Specifically, the second adjustment spring 254 has a second spring body 254a, a first end 254b, and a second end 254c. The second spring body 254a is a part that generates a rotational force, and is disposed on the inner peripheral side of the second adjustment bolt 253. The second end 254b protrudes from the end of the second spring body 254a on the engine side and is hooked on the second adjustment bolt 253.
 例えば、第2端254bは第2アジャストボルト253の第2引っ掛け孔253dに挿入されている。第2端254cは、第2スプリング本体254aの第2スライドブッシュ252側の端部から突出しており、第2スライドブッシュ252に引っ掛けられている。例えば、第2端254cは第2スライドブッシュ252の第2スリット252cに挿入されている。第2スライドブッシュ252は第2支持孔263bに締まり嵌めされているので、第2スライドブッシュ252が第2プレッシャプレート49に対して軸方向に移動したり、あるいは回転したりすると、第2スライドブッシュ252と第2プレッシャプレート49との間には比較的大きな摺動抵抗が発生する。第2アジャストスプリング254が第2アジャストボルト253に付与する回転力は第2スライドブッシュ252を回転させるほど大きくはないので、第2スライドブッシュ252は第2プレッシャプレート49に対する第2アジャストスプリング254の回転を規制することができる。 For example, the second end 254b is inserted into the second hooking hole 253d of the second adjusting bolt 253. The second end 254c protrudes from the end of the second spring body 254a on the second slide bush 252 side, and is hooked on the second slide bush 252. For example, the second end 254 c is inserted into the second slit 252 c of the second slide bush 252. Since the second slide bush 252 is tightly fitted in the second support hole 263b, when the second slide bush 252 moves or rotates in the axial direction with respect to the second pressure plate 49, the second slide bush 252 is fitted. A relatively large sliding resistance is generated between 252 and the second pressure plate 49. Since the rotational force applied to the second adjustment bolt 253 by the second adjustment spring 254 is not so great as to rotate the second slide bush 252, the second slide bush 252 rotates the second adjustment spring 254 relative to the second pressure plate 49. Can be regulated.
 第2ストッパ251は、第2スライドブッシュ252に固定されており、第2フライホイール4に対する第2プレッシャプレート49の軸方向の移動を規制する。具体的には、第2ストッパ251は、第1規制リング251aと、第2規制リング251bと、を有している。第1規制リング251aおよび第2規制リング251bは、いわゆるスナップリングであり、第2スライドブッシュ252に装着されている。第1規制リング251aは第2円板部43のエンジン側(第2プレッシャプレート49側)に配置されており、第2規制リング251bは第2円板部43のトランスミッション側に配置されている。動力伝達時において、第2規制リング251bと第2円板部43との間には隙間G2が形成されている。この隙間G2はレリーズ時の第2プレッシャプレート49のリフト量に相当している。したがって、第2摩擦部67が摩耗すると、第1規制リング251aが第2円板部43に当接し、第2スライドブッシュ252を第2プレッシャプレート49に対して軸方向に移動させる。この結果、隙間G2が常に一定に保たれるので、第2円板部43および第2ストッパ251により第2プレッシャプレート49のリフト量が一定に保たれる。 The second stopper 251 is fixed to the second slide bush 252 and restricts the axial movement of the second pressure plate 49 relative to the second flywheel 4. Specifically, the second stopper 251 has a first restriction ring 251a and a second restriction ring 251b. The first restriction ring 251 a and the second restriction ring 251 b are so-called snap rings, and are attached to the second slide bush 252. The first restriction ring 251 a is disposed on the engine side (second pressure plate 49 side) of the second disk part 43, and the second restriction ring 251 b is disposed on the transmission side of the second disk part 43. At the time of power transmission, a gap G2 is formed between the second restriction ring 251b and the second disc portion 43. This gap G2 corresponds to the lift amount of the second pressure plate 49 at the time of release. Therefore, when the second friction portion 67 is worn, the first restriction ring 251 a comes into contact with the second disc portion 43 and moves the second slide bush 252 in the axial direction with respect to the second pressure plate 49. As a result, the gap G2 is always kept constant, so that the lift amount of the second pressure plate 49 is kept constant by the second disk portion 43 and the second stopper 251.
 第2スライドブッシュ252、第2アジャストボルト253および連結ロッド79は同心円状に配置されている。具体的には図4に示すように、第2スライドブッシュ252、第2アジャストボルト253および連結ロッド79の中心軸はラインB2となっている。
 <クラッチ装置1の基本動作>
 クラッチ装置1の基本動作について説明する。図1~図3に示す状態は、駆動機構7により第1クラッチC1および第2クラッチC2に押付力が付与されていない状態であり、第1クラッチC1および第2クラッチC2で動力伝達が行われていない状態である。この状態では、第1プレッシャプレート39は第1ストラッププレート(図示せず)により図1~図3に示す軸方向位置に保持されており、第2プレッシャプレート49は第2ストラッププレート(図示せず)により図1~図3に示す軸方向位置に保持されている。エンジンから動力が入力回転体10に伝達されると、入力回転体10、第1プレッシャプレート39、第2プレッシャプレート49および駆動機構7は一体回転する。第1入力軸91が支持部材35を介して第1ベアリング34を支持しており、第1ベアリング34が第1フライホイール3を回転可能に支持している。また、第2入力軸92が第2ベアリング44を支持しており、第2ベアリング44が第2フライホイール4を回転可能に支持している。このような構成により、入力回転体10の回転が安定する。
The second slide bush 252, the second adjustment bolt 253, and the connecting rod 79 are arranged concentrically. Specifically, as shown in FIG. 4, the central axes of the second slide bush 252, the second adjustment bolt 253, and the connecting rod 79 are a line B2.
<Basic operation of clutch device 1>
The basic operation of the clutch device 1 will be described. The state shown in FIGS. 1 to 3 is a state in which no pressing force is applied to the first clutch C1 and the second clutch C2 by the drive mechanism 7, and power is transmitted by the first clutch C1 and the second clutch C2. It is not in a state. In this state, the first pressure plate 39 is held at the axial position shown in FIGS. 1 to 3 by the first strap plate (not shown), and the second pressure plate 49 is the second strap plate (not shown). ) Is held at the axial position shown in FIGS. When power is transmitted from the engine to the input rotator 10, the input rotator 10, the first pressure plate 39, the second pressure plate 49, and the drive mechanism 7 rotate integrally. The first input shaft 91 supports the first bearing 34 via the support member 35, and the first bearing 34 supports the first flywheel 3 in a rotatable manner. Further, the second input shaft 92 supports the second bearing 44, and the second bearing 44 supports the second flywheel 4 so as to be rotatable. With such a configuration, the rotation of the input rotating body 10 is stabilized.
 例えば、車両が第1速で発進する際、トランスミッションの第1入力軸91側が第1速に切り替えられ、第1駆動機構7Aの第1駆動ベアリング76が第1アクチュエータ(図示せず)によりエンジン側に押される。この結果、第1突起75aを支点として第1ダイヤフラムスプリング71が弾性変形し、第2支持プレート73がエンジン側に押される。第2支持プレート73が第1ダイヤフラムスプリング71を介して押されると、中間部材78および第1プレッシャプレート39がエンジン側に移動する。この結果、第1クラッチディスク組立体5の第1摩擦部57が第1プレッシャプレート39と第1フライホイール3(より詳細には、第1円板部33)との間に挟み込まれ、第1クラッチディスク組立体5を介して第1入力軸91に動力が伝達される。これらの動作により、車両は第1速で発進を開始する。 For example, when the vehicle starts at the first speed, the first input shaft 91 side of the transmission is switched to the first speed, and the first drive bearing 76 of the first drive mechanism 7A is engine-side by the first actuator (not shown). Pressed. As a result, the first diaphragm spring 71 is elastically deformed with the first protrusion 75a as a fulcrum, and the second support plate 73 is pushed to the engine side. When the second support plate 73 is pushed through the first diaphragm spring 71, the intermediate member 78 and the first pressure plate 39 move to the engine side. As a result, the first friction portion 57 of the first clutch disc assembly 5 is sandwiched between the first pressure plate 39 and the first flywheel 3 (more specifically, the first disc portion 33), and the first Power is transmitted to the first input shaft 91 via the clutch disk assembly 5. By these operations, the vehicle starts to start at the first speed.
 第1速から第2速への変速時には、トランスミッションの第2入力軸92側が第2速に切り替えられる。トランスミッションが第2速の状態で、第1クラッチC1の解除とほぼ同時に第2クラッチC2が連結状態に切り替えられる。
 具体的には、第1駆動機構7Aに付与されている押し付け荷重が解放され、第1駆動ベアリング76がトランスミッション側に戻る。この結果、第1ダイヤフラムスプリング71の状態が図1~図3に示す状態に戻り、第1クラッチC1を介した動力伝達が解除される。
When shifting from the first speed to the second speed, the second input shaft 92 side of the transmission is switched to the second speed. When the transmission is in the second speed state, the second clutch C2 is switched to the connected state almost simultaneously with the release of the first clutch C1.
Specifically, the pressing load applied to the first drive mechanism 7A is released, and the first drive bearing 76 returns to the transmission side. As a result, the state of the first diaphragm spring 71 returns to the state shown in FIGS. 1 to 3, and the power transmission via the first clutch C1 is released.
 一方で、第2駆動機構7Bの第2駆動ベアリング77が第2アクチュエータ(図示せず)によりエンジン側に押される。この結果、支持突出部43aを支点として第2ダイヤフラムスプリング72が弾性変形し、第3支持プレート74がトランスミッション側に引っ張られる。第3支持プレート74が第2ダイヤフラムスプリング72により押されると、連結ロッド79および第2プレッシャプレート49がトランスミッション側に移動する。この結果、第2クラッチディスク組立体6の第2摩擦部67が第2プレッシャプレート49と第2フライホイール4(より詳細には、第2円板部43)との間に挟み込まれ、第2クラッチディスク組立体6を介して第2入力軸92に動力が伝達される。これらの動作により、変速段が第1速から第2速に切り替えられる。 On the other hand, the second drive bearing 77 of the second drive mechanism 7B is pushed to the engine side by a second actuator (not shown). As a result, the second diaphragm spring 72 is elastically deformed with the support protrusion 43a as a fulcrum, and the third support plate 74 is pulled toward the transmission side. When the third support plate 74 is pushed by the second diaphragm spring 72, the connecting rod 79 and the second pressure plate 49 move to the transmission side. As a result, the second friction portion 67 of the second clutch disk assembly 6 is sandwiched between the second pressure plate 49 and the second flywheel 4 (more specifically, the second disc portion 43), and the second Power is transmitted to the second input shaft 92 via the clutch disk assembly 6. With these operations, the gear position is switched from the first speed to the second speed.
 <第1摩耗追従機構100の動作>
 第1クラッチC1の連結時において、第1駆動機構7Aにより第1プレッシャプレート39がエンジン側に押されると、図8に示すように、第1スライドブッシュ152が第1フライホイール3の第1円板部33と接触する。第1摩擦部57が摩耗すると、第1スライドブッシュ152が第1円板部33に当接してから、さらに第1プレッシャプレート39が第1駆動機構7Aによりエンジン側に押し込まれる。このとき、第1スライドブッシュ152と第1プレッシャプレート39との間に生じる摺動抵抗は第1駆動機構7Aから第1プレッシャプレート39に付与される押し付け荷重よりも大幅に小さいので、第1スライドブッシュ152が第1プレッシャプレート39と摺動し、図8に示すように、第1プレッシャプレート39が第1スライドブッシュ152に対してエンジン側に移動する。第1摩擦部57が第1プレッシャプレート39と第1円板部33との間に完全に挟み込まれると、第1プレッシャプレート39の移動が停止する。こうして、第1クラッチディスク組立体5を介して動力伝達が行われる。この状態で第1規制部152bと第1当接部153bとの間には、第1摩擦部57の摩耗量G11に相当する隙間が生じる。
<Operation of First Wear Following Mechanism 100>
When the first pressure plate 39 is pushed to the engine side by the first drive mechanism 7A when the first clutch C1 is engaged, the first slide bush 152 is moved to the first circle of the first flywheel 3 as shown in FIG. Contact the plate portion 33. When the first friction portion 57 is worn, the first pressure plate 39 is further pushed into the engine side by the first drive mechanism 7A after the first slide bush 152 comes into contact with the first disc portion 33. At this time, the sliding resistance generated between the first slide bush 152 and the first pressure plate 39 is significantly smaller than the pressing load applied to the first pressure plate 39 from the first drive mechanism 7A. The bush 152 slides on the first pressure plate 39, and the first pressure plate 39 moves to the engine side with respect to the first slide bush 152 as shown in FIG. When the first friction portion 57 is completely sandwiched between the first pressure plate 39 and the first disc portion 33, the movement of the first pressure plate 39 stops. Thus, power transmission is performed via the first clutch disk assembly 5. In this state, a gap corresponding to the wear amount G11 of the first friction portion 57 is generated between the first restricting portion 152b and the first contact portion 153b.
 第1クラッチC1の連結を解除するために第1駆動機構7Aによる押し付け荷重の付与が解除されると、第1ストラッププレートの弾性力により第1プレッシャプレート39は第1フライホイール3に対してトランスミッション側に移動するが、第1スライドブッシュ152の第1引っ掛け部152dが第1ストッパ151のストッパ部151bに当接すると、第1フライホイール3のトランスミッション側への移動は停止する。その後、さらに解除動作を続けると、第1ダイヤフラムスプリング71が第2支持プレート73と分離するため、第1アジャストボルト153に付与される押し付け荷重はほぼゼロとなる。第1アジャストボルト153には第1アジャストスプリング154の回転力が常に作用しているので、第1スライドブッシュ152の第1当接部152bと第1アジャストボルト153の第1ストッパ部153dとの隙間G1がなくなるまで第1アジャストボルト153が回転する。このようにして、第1摩擦部57の摩耗に伴う摩耗追従動作が完了する。 When the application of the pressing load by the first drive mechanism 7A is released to release the connection of the first clutch C1, the first pressure plate 39 is transmitted to the first flywheel 3 by the elastic force of the first strap plate. However, when the first hooking portion 152d of the first slide bush 152 abuts against the stopper portion 151b of the first stopper 151, the movement of the first flywheel 3 toward the transmission side stops. Thereafter, when the releasing operation is further continued, the first diaphragm spring 71 is separated from the second support plate 73, and therefore the pressing load applied to the first adjustment bolt 153 becomes substantially zero. Since the rotational force of the first adjustment spring 154 always acts on the first adjustment bolt 153, the gap between the first contact portion 152b of the first slide bush 152 and the first stopper portion 153d of the first adjustment bolt 153 The first adjustment bolt 153 rotates until G1 disappears. In this way, the wear following operation accompanying the wear of the first friction portion 57 is completed.
 第1アジャストボルト153が第1プレッシャプレート39に対して移動すると、第1アジャストボルト153の第1当接部153bが第1規制部152bと接触する。このとき、第1アジャストスプリング154の回転力により発生する第1アジャストボルト153の軸力よりも第1スライドブッシュ152と第1プレッシャプレート39の第1支持孔163bとの間に生じる軸方向の摺動抵抗の方がはるかに大きい。そのため、第1アジャストボルト153の第1当接部153bが第1スライドブッシュ152の第1規制部152bに当接すると、第1スライドブッシュ152が第1プレッシャプレート39に対して移動せず、第1スライドブッシュ152により第1アジャストボルト153の軸方向の移動が規制され、第1アジャストボルト153の回転が停止する。 When the first adjustment bolt 153 moves relative to the first pressure plate 39, the first contact portion 153b of the first adjustment bolt 153 comes into contact with the first restricting portion 152b. At this time, the axial sliding generated between the first slide bush 152 and the first support hole 163b of the first pressure plate 39 rather than the axial force of the first adjustment bolt 153 generated by the rotational force of the first adjustment spring 154. Dynamic resistance is much greater. Therefore, when the first contact portion 153b of the first adjustment bolt 153 contacts the first restriction portion 152b of the first slide bush 152, the first slide bush 152 does not move with respect to the first pressure plate 39, and The movement of the first adjustment bolt 153 in the axial direction is restricted by the one slide bush 152, and the rotation of the first adjustment bolt 153 stops.
 また、第1スライドブッシュ152と第1プレッシャプレート39の第1支持孔163bとの間に生じる回転方向の摺動抵抗も第1アジャストスプリング154の回転力よりもはるかに大きいので、第1スライドブッシュ152が予期せぬ回転をして第1アジャストスプリング154の回転力を弛緩させてしまうことも起こらない。さらに、このような作用のためクラッチをレリーズした場合に生じがちな第1プレッシャプレート39の軸方向振動で、第1ダイヤフラムスプリング71が第2支持プレート73と断続的に分離した場合でも、第1アジャストボルト153が予期せぬ回転を起こすこともない。 Further, since the sliding resistance in the rotational direction generated between the first slide bush 152 and the first support hole 163b of the first pressure plate 39 is much larger than the rotational force of the first adjustment spring 154, the first slide bush It does not occur that the 152 rotates unexpectedly and relaxes the rotational force of the first adjustment spring 154. Further, even if the first diaphragm spring 71 is intermittently separated from the second support plate 73 due to the axial vibration of the first pressure plate 39 which tends to occur when the clutch is released due to such an action, the first The adjustment bolt 153 does not rotate unexpectedly.
 こうして、図9に示すように、第1摩擦部57に摩耗量G11に相当する分だけ、第1スライドブッシュ152および第1アジャストボルト153が第1プレッシャプレート39に対してトランスミッション側へ移動し、それに伴い、第2支持プレート73が第1プレッシャプレート39に対してトランスミッション側に移動する。言い換えると、第1摩擦部57に摩耗量G11に相当する分だけ、第1プレッシャプレート39が第1スライドブッシュ152および第1アジャストボルト153に対してエンジン側へ移動する。第1摩擦部57が摩耗すれば、上記の動作は第1クラッチC1の連結解除時に繰り返される。 Thus, as shown in FIG. 9, the first slide bush 152 and the first adjustment bolt 153 move toward the transmission side with respect to the first pressure plate 39 by an amount corresponding to the wear amount G11 in the first friction portion 57, Accordingly, the second support plate 73 moves to the transmission side with respect to the first pressure plate 39. In other words, the first pressure plate 39 moves toward the engine side with respect to the first slide bush 152 and the first adjustment bolt 153 by an amount corresponding to the wear amount G11 in the first friction portion 57. If the first friction part 57 is worn, the above operation is repeated when the first clutch C1 is released.
 このように、第1摩耗追従機構100であれば、第1摩擦部57が摩耗しても、第1ダイヤフラムスプリング71と第2支持プレート73とが接している支点位置が概ね一定に保たれる。一度調整が完了すると、送りねじ機構を利用しているので、第1ダイヤフラムスプリング71の押付荷重で、第1アジャストボルト153が逆戻りするようなことも起こらない。また、振動などにより第1アジャストボルト153が過剰に回り、いわゆるオーバーアジャストが発生するおそれもない。したがって、第1摩擦部57の摩耗に起因するクラッチ装置1の性能の変動を効果的に抑制することができる。 As described above, in the first wear following mechanism 100, even if the first friction portion 57 is worn, the fulcrum position where the first diaphragm spring 71 and the second support plate 73 are in contact with each other is kept substantially constant. . Once the adjustment is completed, the feed screw mechanism is used, so that the first adjustment bolt 153 does not reverse due to the pressing load of the first diaphragm spring 71. Further, there is no possibility that the first adjustment bolt 153 rotates excessively due to vibration or the like and so-called over adjustment occurs. Therefore, fluctuations in the performance of the clutch device 1 due to wear of the first friction part 57 can be effectively suppressed.
 また、摩耗量を検出する第1スライドブッシュ152が第1アジャストボルト153の移動を規制しているので、支点位置を調整する機構と摩耗量を検出する機構とを1つの機構にまとめることができる。すなわち、このクラッチ装置1では、第1摩耗追従機構100の小型化が可能となり、さらに、組み立て方法の簡素化や製造コストの低減を実現することができる。 Further, since the first slide bush 152 for detecting the wear amount restricts the movement of the first adjustment bolt 153, the mechanism for adjusting the fulcrum position and the mechanism for detecting the wear amount can be combined into one mechanism. . That is, in the clutch device 1, the first wear tracking mechanism 100 can be downsized, and further, the assembling method can be simplified and the manufacturing cost can be reduced.
 さらに、第1アジャストボルト153が第1ネジ孔163a内に配置されており、第1アジャストボルト153の内周側に第1アジャストスプリング154が配置されている。このため、第1摩耗追従機構100の一部を第1プレッシャプレート39の内部に配置することができ、第1摩耗追従機構100の設置スペースを小さく抑えることができる。
 <第2摩耗追従機構200の動作>
 第2クラッチC2の連結時において、第2駆動機構7Bより第2プレッシャプレート49がトランスミッション側に押されると、図10に示すように、第2スライドブッシュ252に装着された第1規制リング251aが第2フライホイール4の第2円板部43と接触する。第2摩擦部67が摩耗すると、第1規制リング251aが第2円板部43に当接してから、さらに第2プレッシャプレート49が第2駆動機構7Bによりトランスミッション側に押し込まれる。このとき、第2スライドブッシュ252と第2プレッシャプレート49との間に生じる摺動抵抗は第2駆動機構7Bから第2プレッシャプレート49に付与される押し付け荷重よりも大幅に小さいので、第2スライドブッシュ252が第2プレッシャプレート49と摺動し、図10に示すように、第2プレッシャプレート49が第2スライドブッシュ252に対してトランスミッション側に移動する。第2摩擦部67が第2プレッシャプレート49と第2円板部43との間に完全に挟み込まれると、第2プレッシャプレート49の移動が停止する。こうして、第2クラッチディスク組立体6を介した動力伝達が行われる。この状態で第2規制部252bと第2当接部253bとの間には第2摩擦部67の摩耗量G12に相当する隙間が生じる。
Further, the first adjustment bolt 153 is disposed in the first screw hole 163a, and the first adjustment spring 154 is disposed on the inner peripheral side of the first adjustment bolt 153. For this reason, a part of the first wear tracking mechanism 100 can be disposed inside the first pressure plate 39, and the installation space of the first wear tracking mechanism 100 can be kept small.
<Operation of Second Wear Following Mechanism 200>
When the second clutch C2 is engaged, when the second pressure plate 49 is pushed to the transmission side by the second drive mechanism 7B, the first restriction ring 251a attached to the second slide bush 252 is moved as shown in FIG. It contacts the second disc part 43 of the second flywheel 4. When the second friction portion 67 is worn, the second pressure plate 49 is further pushed to the transmission side by the second drive mechanism 7B after the first regulating ring 251a contacts the second disc portion 43. At this time, the sliding resistance generated between the second slide bush 252 and the second pressure plate 49 is significantly smaller than the pressing load applied to the second pressure plate 49 from the second drive mechanism 7B. The bush 252 slides with the second pressure plate 49, and the second pressure plate 49 moves to the transmission side with respect to the second slide bush 252 as shown in FIG. When the second friction portion 67 is completely sandwiched between the second pressure plate 49 and the second disc portion 43, the movement of the second pressure plate 49 stops. Thus, power transmission through the second clutch disk assembly 6 is performed. In this state, a gap corresponding to the wear amount G12 of the second friction portion 67 is generated between the second restricting portion 252b and the second contact portion 253b.
 第2クラッチC2の連結を解除するために第2駆動機構7Bによる押し付け荷重の付与が解除されると、第2ストラッププレートの弾性力により第2プレッシャプレート49は第2フライホイール4に対してトランスミッション側に移動するが、第2スライドブッシュ252に固定された第2ストッパ251の第2規制リング251bが第2フライホイール4の第2貫通孔41dに当接すると、第2フライホイール4のトランスミッション側への移動が停止する。その後、さらに解除動作を続けると、第2ダイヤフラムスプリング72が第3支持プレート74と分離するため、第2アジャストボルト253に付与される押し付け荷重はほぼゼロになる。第2アジャストボルト253には第2アジャストスプリング254の回転力が常に作用しているので、第2スライドブッシュ252の第2規制部252bと第2アジャストボルト253の第2当接部253bとの間の隙間G12がなくなるまで第2アジャストボルト253が回転する。このようにして第2摩擦部67の摩耗に伴う摩耗追従動作が完了する。 When the application of the pressing load by the second drive mechanism 7B is released to release the connection of the second clutch C2, the second pressure plate 49 is transmitted to the second flywheel 4 by the elastic force of the second strap plate. When the second regulating ring 251b of the second stopper 251 fixed to the second slide bush 252 contacts the second through hole 41d of the second flywheel 4, the transmission side of the second flywheel 4 is moved The movement to stops. Thereafter, when the releasing operation is further continued, the second diaphragm spring 72 is separated from the third support plate 74, so that the pressing load applied to the second adjustment bolt 253 becomes almost zero. Since the rotational force of the second adjustment spring 254 always acts on the second adjustment bolt 253, the second adjustment bolt 253 is between the second restriction portion 252 b of the second slide bush 252 and the second contact portion 253 b of the second adjustment bolt 253. The second adjustment bolt 253 rotates until the gap G12 disappears. In this way, the wear following operation accompanying the wear of the second friction portion 67 is completed.
 第2アジャストボルト253が第2プレッシャプレート49に対して移動すると、第2アジャストボルト253の第2当接部253bが第2規制部252bと接触する。このとき、第2アジャストスプリング254の回転力により発生する第2アジャストボルト253の軸力よりも第2スライドブッシュ252と第2プレッシャプレート49の第2支持孔263bとの間に生じる軸方向の摺動抵抗の方がはるかに大きい。そのため、第2アジャストボルト253の第2当接部253bが第2スライドブッシュ252の第2規制部252bに当接すると、第2スライドブッシュ252が第2プレッシャプレート49に対して移動せず、第2スライドブッシュ252により第2アジャストボルト253の軸方向の移動が規制され、第2アジャストボルト253の回転が停止する。 When the second adjustment bolt 253 moves relative to the second pressure plate 49, the second contact portion 253b of the second adjustment bolt 253 comes into contact with the second restricting portion 252b. At this time, the axial sliding generated between the second slide bush 252 and the second support hole 263b of the second pressure plate 49 rather than the axial force of the second adjustment bolt 253 generated by the rotational force of the second adjustment spring 254. Dynamic resistance is much greater. Therefore, when the second contact portion 253b of the second adjustment bolt 253 contacts the second restriction portion 252b of the second slide bush 252, the second slide bush 252 does not move relative to the second pressure plate 49, and The movement of the second adjustment bolt 253 in the axial direction is restricted by the two slide bushings 252 and the rotation of the second adjustment bolt 253 stops.
 また、第2スライドブッシュ252と第2プレッシャプレート49の第2支持孔263bとの間に生じる回転方向の摺動抵抗も第2アジャストスプリング254の回転力よりもはるかに大きいので、第2スライドブッシュ252が予期せぬ回転をして第2アジャストスプリング254の回転力を弛緩させてしまうことも起こらない。さらに、このような作用のためクラッチをレリーズした場合に生じがちな第2プレッシャプレート49の軸方向振動で、第2ダイヤフラムスプリング72が第2支持プレート73と断続的に分離した場合でも、第2アジャストボルト253が予期せぬ回転を起こすこともない。 Further, since the sliding resistance in the rotational direction generated between the second slide bush 252 and the second support hole 263b of the second pressure plate 49 is much larger than the rotational force of the second adjustment spring 254, the second slide bush The 252 does not rotate unexpectedly and the rotational force of the second adjustment spring 254 does not relax. Further, even if the second diaphragm spring 72 is intermittently separated from the second support plate 73 due to the axial vibration of the second pressure plate 49 that tends to occur when the clutch is released due to such an action, the second The adjustment bolt 253 does not rotate unexpectedly.
 こうして、図11に示すように、第2摩擦部67に摩耗量G12に相当する分だけ、連結ロッド79、第2スライドブッシュ252および第2アジャストボルト253が第2プレッシャプレート49に対してトランスミッション側へ移動し、それに伴い、第3支持プレート74が第2プレッシャプレート49に対してトランスミッション側に移動する。言い換えると、第2摩擦部67に摩耗量G12に相当する分だけ、第2プレッシャプレート49が第2スライドブッシュ252および第2アジャストボルト253に対してエンジン側に移動する。第2摩擦部67が摩耗していれば、上記の動作は第2クラッチC2の連結解除時に繰り返される。 Thus, as shown in FIG. 11, the connecting rod 79, the second slide bush 252 and the second adjustment bolt 253 are moved to the second friction portion 67 by the amount corresponding to the wear amount G12. Accordingly, the third support plate 74 moves to the transmission side with respect to the second pressure plate 49. In other words, the second pressure plate 49 moves to the engine side with respect to the second slide bush 252 and the second adjustment bolt 253 by an amount corresponding to the wear amount G12 in the second friction portion 67. If the second friction portion 67 is worn, the above operation is repeated when the second clutch C2 is released.
 このように、第2摩耗追従機構200であれば、第2摩擦部67が摩耗しても、第2ダイヤフラムスプリング72と第3支持プレート74とが接している支点位置が概ね一定に保たれる。一度調整が完了すると、送りねじ機構を利用しているので、第2ダイヤフラムスプリング72の押付荷重で、第2アジャストボルト253が逆戻りするようなことも起こらない。また、振動などにより第2アジャストボルト253が過剰に回り、いわゆるオーバーアジャストが発生するおそれもない。したがって、第2摩擦部67の摩耗に起因するクラッチ装置1の性能の変動を効果的に抑制することができる。 Thus, with the second wear following mechanism 200, even if the second friction portion 67 is worn, the fulcrum position where the second diaphragm spring 72 and the third support plate 74 are in contact with each other is kept substantially constant. . Once the adjustment is completed, since the feed screw mechanism is used, the second adjustment bolt 253 does not reversely move due to the pressing load of the second diaphragm spring 72. Further, there is no possibility that the second adjustment bolt 253 rotates excessively due to vibration or the like and so-called over-adjustment occurs. Therefore, fluctuations in the performance of the clutch device 1 due to wear of the second friction part 67 can be effectively suppressed.
